[FFmpeg-devel] [PATCH] matroskaenc: Warning message when RAWVIDEO have unsupported colour space.

Show warning if the resulting file is expected to be unplayable.
The warning also has a hint about NUT format which support more pixel
formats for rawvideo data.

The file is muxed anyway, as it can be useful for some special tools.
